I recently saw an add for a product I am excited for (although most blind people I know prefer Siri):

For anyone who is curious:

The “screen” portion says: welcome to red-dot (or redcomdot; probably the former)

1 2 3 4 5 is listed in the column down the left side of the keypad, and 6 7 8 9 0 is listed down the right side.

I’m assuming that typing characters would be done using the 3×2 pad between the two columns of numbers.
